摘　　要：针对川渝气区须家河储层加砂压裂工艺特点,进行压裂后气举排液工艺设计方法研究,并研制出抗外压90MPa气举阀QJF254-2H、内径62mm整体式气举工作筒。在3口现场试验井上实施成功,证明工艺设计方法合理,工具工作可靠,工艺排液速度快,不动管柱即可实现压裂后气举返排,既简化了作业程序,又能达到缩短试油周期的目的。In view of the characteristics of sand fracturing at Xujiahe reservoir,this paper discussed fracturing afterwards gas lifting and liquid unloading methods.A gas-lift valve(QJF254-2H)with 90MPa external pressure resistance and an integral gas-lift barrel with 62mm inner diameter were introduced in this paper.Successful application in 3 wells testified that the gas lift design was proper and tools working condition was reliable.Liquid unloading velocity was fast.Gas lifting unlading after fracturing without pipe string tripping was realized,thus not only simplified the operation procedures,but also shortened the production test cycle.
